Abstract :
A novel design is described for UWB- circularly polarized square slot antenna (CPSSA). Circular polarization (CP) operations can be attained using a fork-shaped feed line protruded from the feeding coplanar waveguide (CPW). The CP bandwidth can be significantly enhanced by implanting a pair of inverted-L, and inverted-F grounded strips into three corners of the slot and truncate remained corner. The designed antenna exhibits an impedance bandwidth of 10GHz. Multi regions exhibits CP with FBW that varies from 5% to 40%.
